Never in the darkest days of Klez was it this bad. Overnight I got 300+ virus mails from "support@microsoft.com". THREE HUNDRED! Fortunately, SpamAssassin was ready.
For anyone else caught by this, here's my rules:
header FROM_SUPPORTMICROSOFT From =~
/\bsupport\@microsoft\.com\b/
describe FROM_SUPPORTMICROSOFT From: support@microsoft.com (virus)
score FROM_SUPPORTMICROSOFT 1.5
rawbody BODY_SUPPORTMICROSOFT/^All information is in the attached file\.\s*$/m
describe BODY_SUPPORTMICROSOFT support@microsoft.com virus body
score BODY_SUPPORTMICROSOFT 1.5
meta SUPPORTMICROSOFT_VIRUS FROM_SUPPORTMICROSOFT && BODY_SUPPORTMICROSOFT
describe SUPPORTMICROSOFT_VIRUS support@microsoft.com virus
score SUPPORTMICROSOFT_VIRUS 6.5
